LCA-based tools for the selection of building materials in Singapore

Abstract

In promoting sustainable construction in Singapore, regulations were introduced in 2009 that mandates for construction projects to meet GreenMark requirements. However, GreenMark does not have an impact in the selection of building materials. When it comes to evaluating the environmental burdens of building materials, Life Cycle Assessment (LCA) is a scientifically reliable method that can be used. Thus a survey was conducted to find out if LCA methods are being used in Singapore and to seek opinion regarding a possible integration of LCA into the BCA GreenMark Scheme. It was found that an overwhelming proportion of the respondents were not even aware on the conceivable use of LCA in making building material choices, but showed positive environmental attitude and generally support the integration of LCA methods into GreenMark. To conclude a LCA database on local building materials should be established and merged into currently available tools in the local industry. © 2012 ASCE.
